## Features
Features of bottom include:
- CPU widget to show a visual representation of per-core usage. Average CPU display also exists.
- Memory widget to show a visual representation of both RAM and SWAP usage.
- Networks widget to show a log-based visual representation of network usage.
- Sortable and searchable process widget. Searching supports regex, and you can search by PID and process name.
- Disks widget to display usage and I/O per second.
- Temperature widget to monitor detected sensors in your system.
The compatibility of each widget and operating systems are, as of version 0.1.0, as follows:
2020-01-19 07:02:44 +00:00
| OS/Widget | CPU | Memory | Disks | Temperature | Processes | Networks |
| ------------------------------ | -------- | -------- | -------- | --------------------- | --------- | --------------------------------------------- |
| Linux (tested on Arch Linux) | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
| Windows (tested on Windows 10) | ✓ | ✓ | ✓ | Currently not working | ✓ | Partially supported (total RX/TX unavailable) |
| macOS | Untested | Untested | Untested | Untested | Untested | Untested |

2020-01-21 01:09:39 +00:00
In all cases you can install the in-development version by cloning and using `cargo build --release` . Note this is built and tested with Rust Stable (1.40.0 as of writing). You can also get release versions using `cargo install bottom` , or manually building from the [Releases ](https://github.com/ClementTsang/bottom/releases ) page by downloading and building.

### Windows
2020-01-19 07:02:44 +00:00
You may need to install a font like [FreeMono ](https://fonts2u.com/free-monospaced.font ) and use a terminal like cmder for font support to work properly, unfortunately.
